Understand LOE of adding an 'Is this Useful' page level metric

[niradatta1-zz]

As a CivicActioner, I want to understand the value of the content I put up online, so I can improve the content for users.

To help, we will look into seeing how best to integrate an 'Is this Useful/thumbs up/down' page-level metric. This can help us understand how relevant and useful the content of a given page is for the user.

@dmundra to research level of effort and feasibility of integrating this metric on our site.
